People have been devising fake arms, legs, noses and virtually every other body part for centuries. Here, a quick look at some of the devices that humans have invented to replace -- or at least approximate -- the irreplaceable.

Hammer Hand

A British veteran uses a specially designed artificial arm to hammer a nail, 1942. The prosthetic was supplied by England’s Ministry of Pensions, created in the midst of WWI to help vets and their dependents.

I think that it is cool to see how far we have come in the development of prosthetic body parts. We have come a long way from false teeth. However, those are still quite popular. My grandpa is actually thinking about getting some for his mouth. http://www.naturaldentureclinic.com.au/about-us.aspx

what a dumb article, completely out of order, not too mention some of things weren't even prostetics. disguises by CIA agents, while cool, are not prostetics as they do not replace a missing body part! And what about hook's hook! the best prostetic in history, not even mentioned! perfect for gutting lost boys and fish.
